Plastic piece found in scrambled eggs

Prefacing this with that I always clean my plates, pans and other things I use to cook eggs, anyways I was wondering is it normal to find a plastic/glasslike material in my scrambled eggs, I know sometimes a shell piece or 2 can get trapped in the cooking adding a slight crunch if you don't prepare the eggs right, however this is something thicker than a shell and translucent, about the width of 5 shell layers if they were stacked with a broken edge on both top and bottom sides with smoothness on the other sides, does anyone know if plastic pieces the size of a corn piece make it into the hens and or eggs, these are store bought so I wouldn't be surprised if they got this low into putting macro plastics in the hens by accident, however if this is just a rare thing eggs do then please let me know, anything helps make what I ate less suspicious to me.
